I apologize for the OT message, but I'm bleary-eyed from searching
online documentation and archives and I'm hoping some of you gurus out
there who have experience with Linux as well as FreeBSD may have a
solution:
We've got a RedHat 6.0 box (Intel PIII) with a Mylex DAC960 Hardware
RAID Controller configured for RAID-5 with seven 9GB SCSI drives.
We had to reboot the system last night, and on restart fsck failed for
the RAID device with the error message:
Block bitmap for group 256 is not in group
followed by
/dev/rd/c0d2p1: Unexpected inconsistency, run fsck manually
Running fsck manually produced the error message:
e2fsck: bad magic number in superblock while trying to open
/dev/rd/c0d2p1
Trying again using e2fsck -B and varying block sizes of 1024, 2048, etc
got:
Group descriptor look bad... trying backup blocks
e2fsck: bad magic number in superblock while trying to open
/dev/rd/c0d2p1
However, the DAC controller's consistency check completed at 100% with
no errors, and the driver reported no problems during boot.
Is there anything that can be done to solve this and save the
filesystem?
Thanks,
David
